Who's Mr. /usr/bin/make?
I want make to silently ignore a failure to find a .include file. The
reason I want this is because in the next release of X imake will generate
Makefiles that can use include files for dependencies if the system's make
supports it.
N.B. ClearMake, SGI, and Digital, makes all have include directives that
silently ignore a failure to find the include file, so this isn't a new
idea. And if you think about it, it's really a necessity to ignore the
failure otherwise you have a chick-or-the-egg problem when you try to do
a `make depend` to generate the include file.
I've appended a trivial patch to the end that gives me what I want. If
this isn't acceptable for some reason I would consider an alternative
directive, e.g. `.sinclude' (documented of course, and I'd do the work)
that does what I want.
Comments?

(note that this patch intentionally does not change the behavior in the
undocumented traditional SYSV include directive processing, although
maybe it should.)
